Non-invasive surveys of mammalian viruses using environmental DNA

Niccolò Alfano, Anisha Dayaram, Jan Axtner, Kyriakos Tsangaras, Marie-Louise Kampmann, Azlan Mohamed, Seth T. Wong, M. Thomas Gilbert, Andreas Wilting & Alex D. Greenwood
This dataset provides supplemental information to interpret the data published in Alfano & Dayaram et al. 2021. The study investigates how environmental DNA (eDNA) and invertebrate-derived DNA (iDNA) can be used to characterize the yet largely unknown virome present in mammalian wildlife. Environmental DNA and iDNA are used to survey biodiversity non-invasively to mitigate difficulties in obtaining wildlife samples, particularly in remote areas or for rare species. Recently, eDNA/iDNA were used to monitor known wildlife...

Data from: Using singleton densities to detect recent selection in Bos taurus

Matthew Hartfield, Nina Aagaard Poulsen, Bernt Guldbrandtsen & Thomas Bataillon
Many quantitative traits are subject to polygenic selection, where several genomic regions undergo small, simultaneous changes in allele frequency that collectively alter a phenotype. The widespread availability of genome data, along with novel statistical techniques, has made it easier to detect these changes. We apply one such method, the ‘Singleton Density Score’, to the Holstein breed of Bos taurus to detect recent selection (arising up to around 740 years ago). We identify several genes as...

Data from: Biosystematics of Platanthera bifolia s.l. (Orchidaceae): Inferences from analysis of Scandinavian population samples

Henrik Æ. Pedersen & Conny Bruun Asmussen Lange
Over the years, various authors have (sub)divided the Eurasian moth pollinated Platanthera bifolia into several taxa. Advanced studies using multivariate morphometric analysis and/or genetic fingerprinting have all included regions where the situation appears particularly complex. With the aim to resolve variation patterns in a region where the situation seems less complex, we analysed morphometric and AFLP data from 13 Scandinavian populations using a range of uni- and multivariate statistical methods. Variation was largely continuous, though...

Data from: Long-term trends in the occupancy of ants revealed through use of multi-sourced datasets

Julie Sheard, Carsten Rahbek, Robert Dunn, Nathan Sanders & Nick Isaac
We combined participatory science data and museum records to understand long-term changes in occupancy for 29 ant species in Denmark over 119 years. Bayesian occupancy modelling indicated change in occupancy for 15 species: five increased, four declined and six showed fluctuating trends. We consider how trends may have been influenced by life-history and habitat changes. Our results build on an emerging picture that biodiversity change in insects is more complex than implied by the simple...

Microsatellite data from various African buffalo (Syncerus caffer) populations throughout Africa

Pim Van Hooft, Wayne Getz, Ben Greyling, Rasmus Heller, Knut Røed & Armanda Bastos
1280 African buffalo (Syncerus caffer) samples genotyped with up to 19 microsatellites. 1275 samples are from East (12 populations) and southern Africa (4 populations). 5 samples are from central Africa (2 populations).

Harmothoe imbricata MicroCT-scans for 3D reconstruction

Marc Christian Allentoft-Larsen, Brett C. Gonzalez, Joost Daniels, Kakani Katija, Karen Osborn & Katrine Worsaae
Annelids are predominantly found along the seafloor, but over time have colonised a vast diversity of habitats, such as the water column, where different modes of locomotion are necessary. Yet, little is known about their potential muscular adaptation to the continuously swimming required in the water column. The musculature and motility were examined for five scale worm species of Polynoidae (Aphroditiformia, Annelida) found in shallow waters, deep sea and caves that exhibit crawling, occasional swimming...

Antibody features towards VAR2CSA and CSA binding infected erythrocytes in a cohort of pregnant women from PNG

Elizabeth Aitken, Amaya Ortega-Pajares, Agersew Alemu, Wina Hasang, Saber Dini, Holger Unger, Maria Ome-Kaius, Morten Nielsen, Ali Salanti, Joe Smith, Stephen Kent, P Mark Hogarth, Bruce Wines, Julie Simpson, Timon Damelang, Amy Chung & Stephen Rogerson
Plasmodium falciparum causes placental malaria, which results in adverse outcomes for mother and child. P. falciparum infected erythrocytes that express the parasite protein VAR2CSA on their surface can bind to placental chondroitin sulfate-A. It has been hypothesized that naturally acquired antibodies towards VAR2CSA protect against placental infection, but it has proven difficult to use measures of antibody to identify individuals protected from disease. We used a systems serology approach to identify naturally acquired antibody features...

Data from: The allometry of sound frequency bandwidth in songbirds

Jakob Isager Friis, Joana Sabino, Pedro Santos, Torben Dabelsteen & Goncalo C. Cardoso
Theory predicts that allometric constraints on sound production should be stronger for the lower frequencies of vocalizations than for their higher frequencies, which could originate an allometry for sound frequency bandwidth, but this was never tested. Using song recordings of ca. 1000 passerine species (from >75% passerine genera), we show a significantly steeper allometry for the lower than the higher song frequencies, resulting in a positive allometry of frequency bandwidth: larger species can use wider...

Emergence and radiation of distemper viruses in terrestrial and marine mammals - Input files, bash and R codes for analysing PDV and CDV sequence data

Iben Stokholm, Wendy Puryear, Kaitlin Sawatzki, Steen Wilhelm Knudsen, Thilde Terkelsen, Paul Becher, Ursula Siebert & Morten Tange Olsen
Canine distemper virus (CDV) and phocine distemper virus (PDV) are major pathogens to terrestrial and marine mammals. Yet little is known about the timing and geographical origin of distemper viruses and to what extent it was influenced by environmental change and human activities. To address this, we i) performed the first comprehensive time-calibrated phylogenetic analysis of the two distemper viruses; ii) mapped distemper antibody and virus detection data from marine mammals collected between 1972-2018; iii)...

MERFISH measurements in the mouse ileum

Jeffrey Moffitt, Rosalind Xu, Peter Kharchenko, Viktor Petukhov, Paolo Cadinu, Ruslan Soldatov & Konstantin Khodosevich
Spatial transcriptomics protocols based on in situ sequencing or multiplexed RNA fluorescent hybridization can reveal detailed tissue organization. However, distinguishing the boundaries of individual cells in such data is challenging, and can hamper downstream analysis. Current methods generally approximate cells positions using nuclei stains. We describe a segmentation method, Baysor, which optimizes 2D or 3D cell boundaries considering joint likelihood of transcriptional composition and cell morphology. While Baysor can take into account segmentation based on...
